setOverprint(mode)

Enable or disable support for overprint and overprint simulation in generated thumbnails. Overprint is a device dependent feature and the results will vary depending on the output color space and supported colorants (i.e. CMYK, CMYK+spot, RGB, etc). Default is e_op_pdfx_on.

e_op_on: always enabled; e_op_off: always disabled; e_op_pdfx_on: enabled for PDF/X files only.
Returns:
this object, for call chaining
Type
PDFNet.PDFDoc.ViewerOptimizedOptions

setThumbnailRenderingThreshold(threshold)

For any pages that are not forced to include thumbnails this function adjusts whether we should include them depending on the complexity of the page. This can be used to include fewer or more thumbnails as required by the use case. In particular reducing this value will tend to increase the number of page thumbnails included and vice versa.
Parameters:
Name Type Description
threshold number A number from 0 (include all thumbnails) to 100 (include only the first thumbnail) representing the complexity at which SaveViewerOptimized would include the thumbnail. The default value is 50.
Returns:
this object, for call chaining
Type
PDFNet.PDFDoc.ViewerOptimizedOptions

setThumbnailSize(size)

The maximum allowed length for the thumbnail's height/width. The default thumbnail size is 1024.
Parameters:
Name Type Description
size number the maximum dimension (width or height) that thumbnails will have.
